SPECIFICATION forming part of Letters Patent No. 539,420, dated May 21, 1895. 1

Application filed January 19, 1894' Serial No. 497,387. (No model.)

To all whom it may concern:

Be it known that I, PETER J. CROUSE, of Utica, in the county of Oneida and State of New York, have in vented certain new and useful Improvements in Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

My invention relates to improvements in heaters adapted for water or steam heating.

In the drawings which accompany and form a part of this specification, and in which similar letters and figures of reference refer to corresponding parts in the several views, Figure 1 shows in side elevation, partially in section and with parts broken out, my improved heater arranged as a steam-heater. Fig. 2 shows a sectional view adjacent tothe front end, showing the interior of the fire box. Fig. 3 shows a cross-section adjacent to the rear end, showing in the cross-section the flues and water and steam chambers. Fig. 4 shows a longitudinal section of the device.

Referring to the figures and letters of reference in a more particular description of the device, 1 indicates the body portion of the heater which is in general outline from the side of alocomotive boiler shape and is rectangular in cross-section through the fire-box portion and the boiler portion of the device.

The body portion is provided with a cham her 2 for containing the fire and known as the fire-box, in the bottom of which is provided the grate 3, and below this the ash-pit 4. The fire-box is provided with an inclined feed section 5 terminating at its outer end at the feeddoor 6. Within the body portion of the chamber is a water chamber 7 through which extend from the division wall 8 to the rear end 9, the fiues 10.

The circulation after passing through the fiues 10 passes upward between the end of the heater and the wall 11 into the rectangular flue 12 extending from rear to front along the body of the heater. At the front end of the flue the products of combustion pass thence down the sides of the heater, as indicated by the arrows in 1, to the chimney or smokeflue 13. On top of the body portion of the heater, as shown in Figs. 1 to 4, inclusive, and forming the top wall of the flue 12 I mountthe tank 14, which, in using the construction as a steam heater, is preferably maintained from one-half to two-thirds full of water, as'clearly indicated in Figs. 1 to4 inclusive. The tank 14 is in communication with the body portion of theheater by means of the circulating pipes shownat 15- 15. The tank circulating pipes 15-15 are introduced, somewhat above the bottom of the tank, so that in case the water runs low, a certain amount of water will be retained in the tank and not allowed to be drawn into the body portion proper by the circulating pipes. In connection with the pipes 15, I introduce headers 16 to which the return pipes 17 17 are connected. Above the heater and tank I prefer to provide a drum 17 to act as a steam chamber and which is placed in connection with the tank 14; by two or more pipes 18. The circulating pipes 19 connect with this steam drum.

In addition to the peculiar manner in which the construction is built up, particular attention is directed to the fire-box whereby the prod nets of combustion are super-heated as they pass over crown sheet 20 of the fire box and before passing down the outside of the heater, and by this super-heating of the products ofjcombustion and gases, a reignition of the products of combustion is maintained at this point, producing a complete combustion, thereby deriving the greatest amount of heat from the material consumed. The whole ,heater, except the headers 16 and the drum 17,

is inclosed in a case 21 preferably. of brick, built up a little removed from the sides of the heater, forming the side flues 2222 through which the products of combustion lastly pass in their passage toward the chimney or draft fine, as before mentioned. I

In order to provide additional heating surface, in the fire-box, I provide around the walls of the fire-box a set of pipes, as indicated at A, in pairs, with a double elbow, which are secured in the wall 8 and contain the water when the device is in operation.

What I claim as new, and desire to secure by Letters Patent, is

The combinationin a heater, of the heater body 1 havinga fire-box 2, crownsheet 20 and fines 10, a tank 14 mounted on top of the heater body and extending over the entire length of 5 the body including the crown sheet 20, and providing between the tank and body a draft and combustion flue 12 passing over the length of the body and including the crown sheet 20, and a casing providing flues 22 on the
